Embodiment

[0021] Such as figure 1 As shown, an image acquisition device for real-time acquisition of cable surface images of a cable bridge consists of a fixed platform for installing a USB camera, an image acquisition / control module and an image receiving / processing module arranged on the fixed platform . The image acquisition / control module is wirelessly connected with the image receiving / processing module.

[0022] Such as figure 2 As shown, the positioning hole 1 is used to fix the camera installation platform on the cable crawling robot. It should be noted that the positioning hole 1 is not limited to the schematic figure 2 The position in the center does not limit the number of positioning holes. The position and number of positioning holes 1 are determined according to the specific structure of the cable crawling robot. The camera 2 is a high-definition camera, and its interface is a USB interface, and is installed on the camera support platform 3 . It should be noted that...

Abstract

The invention discloses an image acquisition device used for acquiring a stay cable surface image of a cable-stayed bridge in real time. The image acquisition device comprises an image acquisition / control module and an image receiving / processing module connected with the image acquisition control module. The image acquisition device used for acquiring the stay cable surface image of the cable-stayed bridge in real time overcomes the disadvantages of an existing stay cable surface image acquisition device, such as high cost, low degree of miniaturization, high price, high power consumption, poor real-time performance and complex installation, can lighten work burden of bridge maintainers and can increase the work efficiency.

Description

technical field [0001] The invention relates to the field of real-time image acquisition and transmission, in particular to an image acquisition device for real-time acquisition of cable surface images of a cable bridge. Background technique [0002] The cable-stayed bridge has the advantages of small beam body height, large clearance under the bridge, less material consumption, convenient construction and beautiful appearance, and is increasingly used in bridge design. The cable is the main stress-bearing part of the cable-stayed bridge, and its quality and service life determine the safety of the cable-stayed bridge. The polyethylene protective sheath on the outer layer of the cable is used as an isolation protection device for the stressed member of the cable to avoid direct contact with the complex natural environment. If it is exposed to the complex natural environment for a long time, it will often suffer from various degrees of aging and cracking. The damage of these...
